Getting window title from a particular x y coordinate with negative values

[jadams]

Hello, I found the function below to return a window title under a particular x y coordinate and it works but it treats negative values as the absolute. For instance -1080 is treated the same as 1080. Can anybody update the function to allow negative x y values?

Code: Select all

WinGetAtCoords(x,y,what="Title") 
{     ; by SKAN and Learning one
	; Returns Title/ID/Class/PID of window at given coordinates 
    WinID := DllCall( "GetAncestor", UInt      ; by SKAN
           ,DllCall( "WindowFromPoint", Int,X, Int,Y )
           , UInt, GA_ROOT := 2)
	if (what = "Title" or what = "T") {
		WinGetTitle, WinTitle, ahk_id %WinID%
		Return WinTitle
	}
	else if (what = "ID" or what = "I")
		Return WinID
	else if (what = "Class" or what = "C") {
		WinGetClass, WinClass, ahk_id %WinID%
		Return WinClass
	}
	else if (what = "PID" or what = "P") {
		WinGet, WinPID, PID, ahk_id %WinID%
		Return WinPID
	}
}	; http://www.autohotkey.com/forum/viewtopic.php?p=341120#341120

You could just use MouseGetPos and WinGetTitle. I think you would move the mouse first, so I'm not sure whether that poses a problem. Another approach could be to get the list of windows & their positions, and then see what matches your x and y.

Code: Select all

F3::MsgBox, 64, Window title, % windowTitle(558, 545)

windowTitle(x, y) {
 WinGet, win, List
 Loop, %win% {
  WinGetPos, x1, y1, width, height, % winTitle := "ahk_id" win%A_Index%
  x2 := x1 + width - 1, y2 := y1 + height - 1
  If x between %x1% and %x2%
   If y between %y1% and %y2%
   { WinGetTitle, title, %winTitle%
     Return title
   }
 }
}

Of course, one coordinate could correspond to many windows. This function returns the topmost window title.

That doesn't work because what I need is the title of a window present at a particular coordinate without having activated the window and without knowing anything about the window that's there.

That doesn't work for me... I just need the title at a particular coordinate even when that is not the active window.

You ran my script? What happened when you ran it?

Thank you This still has the same issue though. If you pass a negative coordinate into it it doesn't work. For instance this doesn't work:

MsgBox, 64, Window title, % windowTitle(558, -1080)

OK then. Thank you.

Anybody else have any ideas? It's not uncommon to have negative X Y values if your primary monitor is not the top left monitor. Does anyone know how to get anwindow title at a specific X Y value when the x or y value is negative?

@jadams, The script below shows the position and title of any window, including windows with negative values for their positions. I tested it on my computer with multiple monitors.

Code: Select all

#NoEnv
#Persistent

SetTimer, Timer
return

Timer:
MouseGetPos,x,y
ToolTip % "The title of the window at (" x ", " y ") is`n" WinGetAtCoords(x,y)
return

Esc::ExitApp

WinGetAtCoords(x,y,what="Title") 
{     ; by SKAN and Learning one
	; Returns Title/ID/Class/PID of window at given coordinates 
    WinID := DllCall( "GetAncestor", UInt      ; by SKAN
           ,DllCall( "WindowFromPoint", Int,X, Int,Y )
           , UInt, GA_ROOT := 2)
	if (what = "Title" or what = "T") {
		WinGetTitle, WinTitle, ahk_id %WinID%
		Return WinTitle
	}
	else if (what = "ID" or what = "I")
		Return WinID
	else if (what = "Class" or what = "C") {
		WinGetClass, WinClass, ahk_id %WinID%
		Return WinClass
	}
	else if (what = "PID" or what = "P") {
		WinGet, WinPID, PID, ahk_id %WinID%
		Return WinPID
	}

I hope it helps.
